Abstract
The utility model discloses a light sensing type intelligent display terminal which comprises a display panel and a backlight module. The backlight module is fixed to the back of the display panel and connected with a driving circuit, and a light sensor for sensing external light signals is connected onto the driving circuit. The light sensor of the light sensing type intelligent display terminal in an embodiment of the utility model is used for sensing an external light source and transmits sensing signals to the driving circuit, backlight brightness of the backlight module is adjusted by the driving circuit, accordingly, the display terminal can be automatically adjusted along with change of external light, working energy is saved, and human eyes are protected to a certain degree. In addition, the light sensing type intelligent display terminal in the embodiment can automatically stop working in idle time, and energy is intelligently saved.
Description
Technical field
The utility model relates to the display technology field, is specifically related to a kind of photoinduction formula intelligent display terminal.
Background technology
Along with constantly weeding out the old and bring forth the new of electronic product, display terminals such as mobile phone display screen, computer monitor also emerge in an endless stream, yet consider from the angle of environmental protection and energy saving; These display terminals all can exist the high deficiency of power consumption, and existing display terminal can not reconciled self brightness backlight all the time automatically in the process that extraneous light changes; The user can exist incompatible in the process of using, and crosses when ambient light and can make the backlight darker relatively of display terminal when strong, influences viewing effect; Eyesight is caused damage; In being in the environment at night, the backlight of display terminal again can " brightness superfluous ", causes energy dissipation.
The utility model content
The utility model provides a kind of photoinduction formula intelligent display terminal, can solve display terminal and can not carry out self-regulating problem backlight.
The utility model provides a kind of photoinduction formula intelligent display terminal, comprising: display panel, be fixed on the module backlight at the display panel back side, module backlight connects driving circuit, is connected with the optical inductor of an induction external optical signals on the driving circuit.
As a kind of improved procedure, driving circuit is connected with the CS that is used to control whole display terminal work.
As another improved procedure, display panel also is connected with the signal supervisory instrument that is used to detect shows signal, and signal supervisory instrument connects driving circuit.
Technique scheme can be found out; Since the utility model embodiment utilize optical inductor to external world light source respond to; And send induced signal to driving circuit; By driving circuit module backlight is made the adjusting of backlight illumination, therefore can follow the variation of ambient light and display terminal is made self-regulation.
In addition, signal supervisory instrument can send to driving circuit with detection signal when signal source is closed, thereby closes idle display terminal, saves the energy.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art; To do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art below; Obviously, the accompanying drawing in describing below only is some embodiment of the utility model, for those of ordinary skills; Under the prerequisite of not paying creative work, can also obtain other accompanying drawing according to these accompanying drawings.
Fig. 1 is the structured flowchart of photoinduction formula intelligent display terminal among the utility model embodiment;
Fig. 2 is the entity structure diagram of photoinduction formula intelligent display terminal among the utility model embodiment.
Embodiment
To combine the accompanying drawing among the utility model embodiment below, the technical scheme among the utility model embodiment is carried out clear, intactly description, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making all other embodiment that obtained under the creative work prerequisite, all belong to the scope of the utility model protection.
Embodiment:
As shown in Figure 1; The utility model embodiment provides a kind of photoinduction formula intelligent display terminal; Comprise: display panel, be fixed on the module backlight at the display panel back side, module backlight connects driving circuit, is connected with the optical inductor of an induction external optical signals on the driving circuit.Display panel has comprised signal scanning driving circuit and LCDs, and module backlight is mainly used in provides backlight, is made up of backlight drive circuit and backlight.Backlight among the utility model embodiment is the LED lamp.Driving circuit belongs to governor circuit, is mainly used in the driving voltage of regulating module backlight.Receive the induced signal of optical inductor when driving circuit after; Judge brightness of outside light according to induced signal, if ambient light intensity is bigger, then driving circuit can be controlled the driving voltage rising of module backlight; Increase the brightness of display terminal; If ambient light intensity is less or do not have an ambient light, then the driving circuit driving voltage that can control module backlight suitably descends, to reduce energy loss.It is understandable that driving circuit also has other control function, will make detailed introduction below.
Particularly, driving circuit is connected with the CS that is used to control whole display terminal work, and display panel also is connected with the signal supervisory instrument that is used to detect shows signal, and signal supervisory instrument connects driving circuit.
In the process of using; Display panel connects outside signal source, and this signal source can be the video card of host computer, also can be the conversion of signals terminal of televisor; In case signal source is closed; For example use and but do not close display terminal after closing host computer, then signal supervisory instrument can detect the signal source that display panel connects and is in closed condition, then can send detection signal and give driving circuit; Driving circuit is then controlled the CS that is connected with external power source and is turn-offed, thereby stops the work of display terminal.
The entity structure of the photoinduction formula intelligent display terminal among the utility model embodiment is as shown in Figure 2; Each circuit module is installed on the shell 2 of display terminal; Wherein, Display panel and module backlight are installed 201 places in the drawings, and driving circuit, signal supervisory instrument and CS are installed 202 places in the drawings, and optical inductor is installed 203 places in the drawings.
With respect to existing display terminal, the photoinduction formula intelligent display terminal among the utility model embodiment can be made self-control to its backlight illumination with ambient light intensity, has practiced thrift the work energy, has the certain protection effect for human eye simultaneously.Photoinduction formula intelligent display terminal among the utility model embodiment section at one's leisure quits work automatically, has realized intellectual power save mode.
More than photoinduction formula intelligent display terminal that the utility model embodiment is provided carried out detailed introduction; Used concrete example among this paper the principle and the embodiment of the utility model are set forth, the explanation of above embodiment just is used to help to understand the core concept of the utility model; Simultaneously, for one of ordinary skill in the art, according to the thought of the utility model, the part that on embodiment and range of application, all can change, in sum, this description should not be construed as the restriction to the utility model.
